The projection portion 24 determines the position of the electronic component 5 in the vertical direction, with the positioning base plate 21, coming into contact with the end of the lower side of the electronic component 5 which is to be housed in the part of the reception area 2c. At the end of the upper side of the terminal partition plate 23, when seen from the vertical direction, the projection portion 24 protrudes into the divided space portion of the terminal side 2j. The projection portion 24 of the present embodiment is also connected to the inner wall surface 20d. The protrusion portion 24 protrudes from the terminal separation plate 23 in each of the adjacent terminal-side divided space portions 2j. In other words, two projection portions 24 which face each other in the longitudinal direction are formed in the single split-space portion of the terminal side 2j. The width of the projection portion 24 in the width direction is formed so that the terminal 4 can penetrate through the end of the protrusion portion 24 at the bus bar side 3 and the separator plate. 22.
    As shown in Fig. 2 and Fig. 3, the dividing wall 25 is provided in the space portion of the upper side 2f. A plurality of dividing walls 25 is formed in the longitudinal direction, depending on the number of electronic components 5 to be received in the receiving space portion 2c. The partition walls 25 divide the space portion of the upper side 2f in the longitudinal direction, and form portions of divided space 2k. Each of the dividing walls 25 in the present embodiment is formed at regular intervals in the longitudinal direction, and the electronic components 5 are individually received in the respective divided space portions 2k. Each of the dividing walls 25 is formed in a planar shape, and is connected to the inner wall surface 20c and the inner wall surface 20d facing in the longitudinal direction of the peripheral wall 20, in the width direction. The dividing wall 25 protrudes upwardly from the locating base plate 21 and the upper side end surface of the terminal separating plate 23 in the vertical direction, and extends towards the upper side opening. 2nd. In other words, the dividing wall 25 continues to the terminal separation plate 23 in the vertical direction, and forms a single plate with the terminal separation plate 23.
    A slot 25a is formed on the dividing wall 25. The rectangular unit 30 of the bus bar 3 must be inserted into the slot 25a. The slot 25a is formed upwardly from the end of the lower side of the dividing wall 25 in the vertical direction. The slot 25a penetrates through the dividing wall 25 in the longitudinal direction, and the adjacent divided space portions 2k are in communication via the slot 25a. The slot 25a faces the positioning base plate 21 in the width direction, and is in communication with the slot 21a. The end of the upper side of the slot 25a is formed in a lower position than the end of the upper side of the dividing wall 25, to limit the movement of the bus bar 3 in the upward direction, when the Bus bar 3 is inserted in the reception space portion 2c.
    In this example, the space portion of the busbar side 2h comprises a busbar holding unit 26 and busbar holding units 27a and 27b. As shown in Fig. 3 and Fig. 4, the bus bar holding unit 26 protrudes from the inner wall surface 20c to the space portion of the bus bar side 2h. When the busbar 3 is housed in the space portion of the busbar side 2h, the busbar holding unit 26 comes into contact with the end of the lower side of the rectangular unit 30 of the busbar. bus 3, and limits the movement of the bus bar 3 in the vertical direction, with the slot 25a. Therefore, the bus bar holding unit 26 holds the bus bar 3, while the rectangular unit 30 of the bus bar 3 is inserted in the slot 25a. The bus bar holding unit 26 protrudes to separate from the inner wall surface 20c from the lower side to the upper side in the vertical direction and is elastically deformable. The bus bar retainers 27a and 27b face in the width direction, and are formed at regular intervals in the longitudinal direction. When the busbar 3 is inserted between the busbar retainers 27a and 27b, the busbar retainers 27a and 27b limit the movement of the busbar 3 in the width direction. The bus bar retainer 27a is formed on the wall facing the inner wall surface 20c, and extends downward from the end surface of the lower side of the locating base plate 21 to at the opening of the lower side 2d. The bus bar retainer 27b is formed on the separator plate 22, and extends downwardly from the bottom side end surface of the locator base plate 21 to the opening of the bottom side 2d. An inclined surface for allowing the bus bar 3 to be easily inserted is formed on each of the lower side ends of the bus bar retainers 27a and 27b. Thus, the end-to-end distance of the inclined surface in the width direction increases towards the lower side.
    A terminal holding unit 28 and terminal retaining units 29a and 29b are provided in each of the divided space portions of the terminal side 2j. As shown in Fig. 4, the terminal holding unit 28 protrudes from the inner wall surface 20d to the terminal gap portion 2j. When terminal 4 is housed in the terminal-side split portion 2j, terminal holding unit 28 is inserted into a recess portion of terminal 4, and holds terminal 4 limiting the movement of terminal 4 in the vertical direction, with the partition plate 22. The terminal holding unit 28 protrudes upwardly to separate from the inner wall surface 20d from the lower side to the upper side in the vertical direction . The terminal holding unit 28 is formed to be resiliently deformable. The terminal retainers 29a and 29b face each other in the width direction, and are formed at regular intervals in the longitudinal direction. When the terminal 4 is inserted between the terminal retaining units 29a and 29b, the terminal retaining units 29a and 29b limit the movement of the terminal 4 in the width direction. The terminal retainer 29a is formed on the partition plate 22, and extends downwardly from the middle of the partition plate 22 to the bottom side opening 2d. The terminal retainer 29b is formed on a wall corresponding to the inner wall surface 20d, and extends downwardly from the end surface of the lower side of the projection portion 24 to the opening on the lower side 2d. An inclined surface for allowing the terminal 4 to be easily inserted is formed on each of the lower side ends of the terminal retaining units 29a and 29b. Thus, the end-to-end distance of the inclined surface in the width direction increases towards the lower side.
    As illustrated in FIG. 2 and FIG. 3, the bus bar 3 is electrically connected to the electronic component 5. The bus bar 3 in the present embodiment distributes and delivers energy that is delivered by the supply, which is not illustrated, to the various electronic instruments mounted on a vehicle which are electrically connected to the bus bar 3, via the electronic components 5 and terminals 4. The bus bar 3 comprises the unit The bus bar 3 is formed in a planar shape, and the rectangular unit 30 and the feed side holding unit 31 are formed in one piece. When the bus bar 3 is housed in the inner space portion 2a, the rectangular unit 30 is housed in the feed space portion 2b and the receiving space portion 2c, and the holding unit the supply side 31 is housed in the feed space portion 2b. In addition, the rectangular unit 30 is inserted into the slot 25a through the slot 21a, and exposed to each of the divided space portions 2k. The rectangular unit 30 is formed such that the end of the upper side becomes narrower in the upward direction. The rectangular unit 30 functions as a leg unit in the bus bar 3, being electrically connected to each of the electronic components 5 in each of the divided space portions 2k. A through hole 30a is formed on the rectangular unit 30 at a portion where the rectangular unit 30 is positioned in the feed space portion 2b. A stud which is electrically connected to the power supply, which is not illustrated, must be inserted into the through hole 30a. The feed side holding unit 31 secures the electrical wire and the like which is connected to the stud inserted in the through hole 30a.
    As illustrated in FIG. 1, the terminal 4 is electrically connected to the electronic component 5. The terminal 4 is mounted on one of the ends of an electric wire, and is electrically connected to the various electronic instruments that are mounted on the vehicle. being electrically connected to the other end of the electrical wire. The terminal 4 is received in the reception space portion 2c, in other words, in each of the terminal-side divided space portions 2j, while the electrical wire is mounted thereon. For example, terminal 4 is made of metal, and includes a terminal tab unit 4a in a planar shape which is formed in a rectangular shape, and an electric wire crimping unit 4b in tubular form which is connected to the terminal. terminal lug unit 4a in the wiring direction of the electrical wire. The terminal tab unit 4a is electrically connected to a load side connection unit 53 by being inserted into the electronic component 5. The electrical wire crimping unit 4b secures the terminal 4 while the electrical wire is electrically connected at terminal 4, crimping the electrical wire arranged inside. The terminal tab unit 4a is formed such that the end of the upper side (end end portion) becomes narrower in the upward direction.
    The electronic component 5 electrically connects the busbar 3 and the terminal 4, and in this example, the electronic component 5 is an element that performs different functions. The electronic component 5 in the present embodiment is a female fuse link 51 which has a slot in the connection portion. The fuse link 51 is incorporated in a portion of a power distribution circuit, and cuts the power distribution circuit when an overcurrent flows. As illustrated in FIG. 4, the fuse link 51 comprises a supply side connection unit 52 and the load side connection unit 53. The supply side connection unit 52 is connected to the bus bar 3 which functions as a terminal on the power supply side such as a battery. The load side connection unit 53 is connected to terminal 4 on the charging side of various electronic instruments in the vehicle. The supply side connection unit 52 and the load side connection unit 53 are electrically connected through a conductive fuse element in a plate form. For example, while a low melting metal wafer is soldered to a band-like conductive unit whose width is narrowed, the fuse element melts when an overcurrent flows through the fuse element, and cuts the electrical connection between the supply-side connection unit 52 and the load-side connection unit 53. For example, the over-current flowing through the fuse element is a current of a predetermined intensity or more, and the fuse element is melted when the current of the predetermined intensity or more flows through the fuse element. The connection units have different shapes depending on the terminals to be connected. In the present embodiment, since a fork-shaped terminal is to be disposed within the fuse link 51, a slot is formed on each of the connection units. When the fuse link 51 is housed in the divided space portion 2k, the bus bar 3 is inserted into the power supply connection unit 52, and the terminal lug unit 4a is inserted into the power supply connection unit 52. load side connection 53.
    A method of assembling the electronic component unit 1 according to the present embodiment will then be described. First, an operator inserts a stud into the through hole 30a of the bus bar 3 and fixes the stud. The operator then fixes the electrical wire or equivalent which is connected to the stud by the feed side holding unit 31. The bus bar 3 is therefore electrically connected to the power supply. The operator then inserts the bus bar 3 upwards through the opening of the lower side 2d towards the space portion of the bus bar side 2h of the receiving element 2. During this process, part of the bus Rectangular unit 30 of the bus bar 3 is positioned within the receiving space portion 2c, and the supply side holding unit 31 is positioned in the feed space portion 2b. The operator inserts busbar 3 further up. Therefore, the end of the upper side of the bus bar 3, in other words, the end of the upper side of the rectangular unit 30 is inserted into the slot 25a through the slot 21a, a part of the rectangular unit 30 is inserted into the slot 25a, and part of the rectangular unit 30 is positioned between the adjacent slots 25a, in other words, in the divided space portion 2k. During this process, the bus bar 3 passes over the bus bar holding unit 26 while elastically deforming the bus bar holding unit 26, and is positioned above the unit. The bus bar 3 is thus held against the receiving member 2 while the rectangular unit 30 is exposed within the divided space portions 2k.
    Then, the operator inserts each of the terminals 4 upwards, through the opening of the lower side 2d to each of the divided space portions of the terminal side 2j of the receiving element 2. The operator inserts each of the terminals 4 further up. Therefore, the end of the upper side of the terminal 4, in other words, the terminal tab unit 4a is positioned in each of the divided space portions 2k, via the base plate of positioning 21 and the inner wall surface 20d. During the process, the terminal tab unit 4a of terminal 4 passes over the terminal holding unit 28 while elastically deforming the terminal holding unit 28, and the holding unit 28 terminal 28 is positioned in the recess portion. The terminal 4 is thus held against the receiving element 2 while the terminal tab unit 4a is exposed within the divided space portion 2k.
    Then, while the rectangular unit 30 and the terminal tab unit 4a are exposed within the divided space portions 2k, the operator inserts each of the fusible links 51, which are the electronic components 5, to the bottom since the opening of the upper 2nd side on each of the parts of divided space 2k. During the process, the fuse link 51 is inserted down, while the supply side connection unit 52 and the load side connection unit 53 face the bus bar 3 and the leg unit. 4a which are exposed in the vertical direction. The operator inserts each of the fuse links 51 further down. Therefore, the rectangular unit 30 is inserted into the supply side connection unit 52, and the terminal leg unit 4a, in other words, the terminal 4 is inserted into the side connection unit. 53. The operator inserts each of the fuse links 51 further downward so that the end of the lower side of the fuse link 51 comes into contact with the locating base plate 21 and the protrusion portion 24. Thus the electronic component 5 is housed in the receiving space portion 2c. The above procedure allows the power supply such as the battery, bus bar 3, electronic component 5, terminal 4, and the various electronic instruments to be electrically connected in the receiving space portion. 2c of the receiving element 2, thus configuring the electronic component unit 1. In the assembly procedure described above, the terminal 4 is received in the receiving element 2, once the bus 3 is housed in the receiving element 2. However, the assembly procedure is not limited thereto and the terminal 4 can be accommodated in the receiving element 2 before the busbar 3.
    As described above, the electronic component unit 1 according to the present embodiment provides the slot 25a in which the rectangular unit 30 of the bus bar 3 is to be inserted, on the dividing wall 25 which is interposed between the adjacent divided space portions 2k in the receiving member 2. Thus, the bus bar 3 is maintained while the rectangular unit 30 is inserted into the slot 25a.
    Therefore, it is possible to allow the rectangular unit 30 to penetrate through the partition wall 25, and expose the rectangular unit 30 within the divided space portions 2k which are adjacent to each other. another interposing the partition wall 25 between them. Therefore, it is possible to electrically connect each of the electronic components 5 to be received in each of the divided space portions 2k, and a single rectangular unit 30 of the bus bar 3. In other words, compared to a bus bar having a shape in which each of the leg units is independently provided and the leg units are connected to the connection unit, the single rectangular unit 30 of the bus bar 3 functions as a leg unit and as a unit connection. Therefore, it is possible to form the outer shape of the bus bar 3 into a single rectangular shape, and to simplify the outer shape. In this way, it is possible to electrically connect the busbar 3 and each of the electronic components 5 within each of the divided space portions 2k, and to simplify the external shape of the busbar 3.
    By simplifying the external shape of the bus bar 3, the form of transfer of a mold for molding the bus bar 3 can also be simplified. Thus, it is possible to reduce the manufacturing cost and the maintenance cost of the mold. Further, compared to the bus bar having the form in which each of the leg units is independently provided and the leg units are connected to the connection unit, the leg unit and the connection unit are formed of in one piece by the single rectangular unit 30. Thus, there is no need to have length to form the leg unit in the vertical direction. Therefore, it is possible to reduce the length in the vertical direction. Further, compared to the bus bar having the form in which each of the leg units is independently provided and the leg units are connected to the connection unit, the form of the leg unit is not limited. Thus, the shape of the leg unit does not need to depend on the size of the electronic component 5 to be accommodated in the divided space portion 2k, in particular the width of the electronic component 5 in the X direction Therefore, even if the size of the receiving element 2 is the same, and the widths of the electronic components to be received differ in the X direction (even if the number of divided space portions 2k to be formed in the receiving element 2 is changed), it is possible to use the same bus bar 3. It is therefore possible to improve the versatility of the bus bar 3, and reduce the manufacturing cost. In addition, in the bus bar 3, when focusing on a part where the electronic component 5 is electrically connected (part corresponding to the leg unit), compared to when the leg units are formed independently, the space between the adjacent portions corresponding to the leg units is filled. Therefore, it is possible to increase the volume of the busbar 3. In this way, even if the electronic component 5 generates heat when power is supplied to the electronic component 5, the busbar 3 can move a greater amount of heat. In addition, it is possible to improve the heat dissipation of the heat displaced in the bus bar 3. Moreover, it is possible to improve the resistance of the bus bar 3, because the leg units are under the shape of the single rectangular unit 30.
    In the electrical connection box 100 according to the present embodiment, the rectangular unit 30 may be exposed within the adjacent divided space portions 2k interposing the dividing wall 25, while maintaining the bus bar 3 while the rectangular unit 30 is inserted into the slot 25a. Therefore, it is possible to electrically connect the busbar 3 and each of the electronic components 5 inside the divided space portions 2k, and to simplify the external shape of the busbar 3.
    Second embodiment
    An electronic component unit and an electrical connection box according to a second embodiment will then be described. Figure 5 is a perspective view of a bus bar according to the second embodiment. Figure 6 is a schematic view of the bus bar according to the second embodiment. The electronic component unit according to the second embodiment is different from the electronic component unit 1 according to the first embodiment in the form of the bus bar 6. A redundant description of the same configuration, of the same actions, and the same effects as those in the first embodiment described above is omitted as much as possible.
    The bus bar 6 is electrically connected to the electronic component 5 and to an electronic component, which is not illustrated. As shown in FIG. 5 and FIG. 6, the bus bar 6 in the present embodiment is formed in a planar shape, and comprises a first rectangular unit 60, a second rectangular unit 61, and a terminal unit fork-shaped 62.
    The first rectangular unit 60 corresponds to the rectangular unit 30 in the first embodiment, and the end of the first rectangular unit 60 on the side of the second rectangular unit 61 in the longitudinal direction is connected to the second rectangular unit 61 The upper end of the first rectangular unit 60 opposite the side of the second rectangular unit 61 in the longitudinal direction is connected to the fork-shaped terminal unit 62. In the bus bar 6 of the present embodiment the first rectangular unit 60 and the second rectangular unit 61 may be perpendicular to one another or intersect each other when viewed from the vertical direction.
    The second rectangular unit 61 engages the bus bar 6 which is held against the receiving element 2 by the bus bar holding unit 26. The end of the second rectangular unit 61 on the side of the first rectangular unit 60 in the width direction is connected to the first rectangular unit 60. An engagement hole 61c which penetrates through a first outer wall 61a and a second outer wall 61b is formed on the second rectangular unit 61 in the middle of the direction of width. The fork-shaped terminal unit 62 electrically connects the bus bar 6 and the electronic component, which is not illustrated, by grasping the electronic component, which is not illustrated. The fork-shaped terminal unit 62 comprises a pair of extension units 62a and a slot 62b. The pair of extension units 62a is separated in the longitudinal direction, and extends upwardly from the end of the upper side of the first rectangular unit 60. The slot 62b is a space between the pair of units. extension 62a, and a portion in which the electronic component, which is not illustrated, is to be inserted. The receiving element 2 is an element that receives the busbar 6, the terminal 4, the electronic component 5, and the electronic component, which is not illustrated. As shown in FIG. 6, the receiving element 2 comprises a main body unit 200 and an extension unit 201 (mixed line in FIG. 6).
    The receiving space portion 2c in the first embodiment is formed in the main body unit 200, and the divided space portions 2k are formed in the main body unit 200 through the dividing wall 25. The main body unit 200 receives the first rectangular unit 60. The end of the main body unit 200 on the side of the extension unit 201 in the longitudinal direction is connected to the extension unit 201. In this example, in a holding state in which the bus bar 6 is held by the bus bar holding unit 26, a distance between the bus bar holding unit 26 and the end of the bus bar upper side of the slot 25a is provided longer than the length of the first rectangular unit 60 in the vertical direction. In other words, in the holding state, when the first rectangular unit 60 comes into contact with the bus bar holding unit 26, in the bus bar 6, a space is formed between the end of the bus bar upper side of the first rectangular unit 60 and the end of the upper side of the slot 25a. The extension unit 201 receives a portion of the bus bar 6, in other words, the second rectangular unit 61. The extension unit 201 comprises a first wall 202, a second wall 203, a portion expansion space 204, an engagement projection, not shown, and a motion limiting unit 205. The first wall 202 extends in the extension direction of the extension unit 201, in other words, the width direction. In a receiving state in which the bus bar 6 is housed in the receiving element 2, the first wall 202 faces the second outer wall 61b of the second rectangular unit 61 in the longitudinal direction. The second wall 203 extends in the width direction parallel to the first wall 202. In the receiving state, the second wall 203 faces the first outer wall 61a of the second rectangular unit 61 in the longitudinal direction. In this example, the expansion space portion 204 is formed between the first wall 202 and the second wall 203.
    When viewed from the width direction, the extension space portion 204 is longer than the thickness of the second rectangular unit 61, in other words, is formed at a wider range. In the receiving state, the space is formed between the second rectangular unit 61 and the first wall 202 as well as between the second rectangular unit 61 and the second wall 203. For example, the engagement projection protrudes from the second wall 203 to the extension space portion 204, and is inserted into the engagement hole 61c. When the engagement projection is inserted into the engagement hole 61c, the bus bar 6 is prevented from falling off the receiving member 2. Even when the engagement projection is inserted into the engagement hole 61c, the bus bar 6 can move relative to the receiving element 2 in a predetermined range. In the present embodiment, the first wall 202 and the second wall 203 are connected to opposite ends on the side of the main body unit 200. The motion limiting unit 205 limits the movement of the bus bar 6 by relative to the receiving member 2 within the receiving member 2. The motion limiting unit 205 faces a portion on which the insertion force of the electronic component, which is not illustrated. , is applied on the busbar 6 located in the same direction, as well as a part maintaining the busbar 6, in a direction which intersects the same direction and in a state of separation of the busbar 6. motion-limiting unit 205 in the present embodiment faces the fork-shaped terminal unit 62 and the bus-bar holding unit 26 formed in the longitudinal direction, in the width direction which is the orthogo direction nal. The motion limitation unit 205 also faces the second rectangular unit 61 in the longitudinal direction. The motion limiting unit 205 is provided between the second rectangular unit 61 and the first wall 202, and projects from the wall surface facing the second rectangular unit 61 of the first wall 202 to the second rectangular unit 61. In the vertical direction, the motion limiting unit 205 is formed on the lower side end of the first wall 202 which faces at least the lower side end of the second outer wall 61b of the second unit. rectangular 61, in the longitudinal direction. In this example, when the busbar 6, which will be described below, rotates around the busbar holding unit 26 in the counterclockwise direction, the motion limiting unit 205 is designed to engage the second rectangular unit 61, before the first rectangular unit 60 contacts the end of the upper side of the slot 25a.
    An action of the bus bar 6 when the electronic component, which is not illustrated, is inserted into the fork-shaped terminal unit 62 will then be described. As shown in Fig. 6, when the electronic component is inserted down into the fork terminal unit 62, the insertion force in a downward direction Cl is applied to the terminal unit. in the form of a fork 62. During the process, the external force is applied on the bus bar 6 in the downward direction Cl due to the insertion force, and the bus bar holding unit 26 enters into When seen from the width direction, the fork-shaped terminal unit 62 on which the insertion force in the downward direction Cl is applied and the bus bar 26 which holds the bus bar 6 from the down direction are separated. Thus, the bus bar holding unit 26 functions as a fulcrum, and when viewed from the width direction, the rotational force to rotate the bus bar 6 around the drive unit. Bus bar hold 26 is applied. Therefore, when viewed from the longitudinal direction, that part of the first rectangular unit 60 which is located at the side of the second rectangular unit 61 with respect to the bus bar holding unit 26 as well as the second rectangular unit 61 try to turn counterclockwise C2 and C3.
    The distance between the second rectangular unit 61 and the bus bar holding unit 26 is the longest, and changes strongly. Thus, the end of the lower side of the second rectangular unit 61 attempts to start moving in the opposite direction to the side of the fork-shaped terminal unit 62 in the upward direction as well as the longitudinal direction. However, because the end of the lower side of the second rectangular unit 61 faces the motion limiting unit 205 in the longitudinal direction, the second rectangular unit 61 comes into contact with the motion limiting unit 205 The rotation of the busbar 6 around the busbar holding unit 26 counterclockwise is therefore eliminated. In other words, it is possible to prevent the insertion force in the downward direction Cl from being used to rotate the bus bar 6 around the bus bar holding unit 26 in the counterclockwise. Therefore, it is possible to prevent the insertion force that is generated when the electronic component, which is not illustrated, is inserted into the fork terminal unit 62 to be increased. In this way, it is possible to prevent the busbar 6 from being deformed, which occurs when the electronic component 5 is inserted in the busbar 6, and to improve the reliability of connection between the electronic component 5 and the bus bar 6.
    In the second embodiment described above, in the holding state, the second rectangular unit 61 and the motion limiting unit 205 are separated. However, the second rectangular unit 61 and the motion limitation unit 205 may be provided to come into contact with each other. In addition, the motion limiting unit 205 may be formed on the second wall 203. In this case, in the vertical direction, the motion limiting unit 205 must be formed on the end of the upper side of the second wall. wall 203 which faces at least the end of the upper side of the first outer wall 61a of the second rectangular unit 61 in the longitudinal direction. On the other hand, the motion limiting unit 205 may be formed on the first wall 202 and the second wall 203. In this case, when viewed from the width direction, the two motion limiting units 205 may be interposed in the second rectangular unit 61 in the vertical direction and the longitudinal direction, diagonally. Thus, the rotation of the bus bar 6 around the bus bar holding unit 26 in the counterclockwise direction can be further suppressed, further preventing the bus bar 6 from being deformed. As a result, it is possible to further improve the reliability of connection between the busbar 6 and the electronic component 5. The electronic component unit and the electrical connection box according to the present embodiments can electrically connect each of the electronic components which is housed in each of the divided space portions and the rectangular unit of the bus bar, since the slot in which the rectangular unit of the bus bar is to be inserted is provided on the dividing wall which is interposed between the adjacent divided space portions in the receiving member, thereby permitting the exposure of the rectangular unit inside the parts of divided space. Therefore, it is possible to electrically connect the busbar and each of the electronic components in each of the divided space portions, and to simplify the external shape of the busbar.
